Product Description

OPTYSIL is a liquid immune stimulant, which activates natural immune systems of plants and stimulates their growth and development. It contains silicon which is easily absorbed by plants, strengthening cell walls and stimulating numerous vital processes in the plant.

OPTYSIL is recommended for foliar application in the cultivation of all types of agricultural and horticultural crops. It may be also used during irrigation (fertigation, watering).

The neutral pH of the preparation ensures its compatibility with commonly used foliar fertilizers and plant protection products.

It is important to use OPTYSIL prophylactically – before stressful conditions appear.

The most important benefits of using OPTYSIL stimulant include:

Increased plant tolerance to adverse growing conditions (e.g. drought and other abiotic stresses)
Limited influence of biotic stress caused by pathogens and/or pest attack
Stimulated root growth in young plants
Improved crop yield, quality and storage parameters.

OPTYSIL as an immunity stimulant is one of the main elements of the strategy to support the natural resistance of plants STRESS CONTROL SYSTEM (SCS).

Directions for Use

OPTYSIL may be used in different fertilisation techniques, including foliar sprays, fertigation, watering.

FOLIAR SPRAYS
OPTYSIL is intended for foliar application in the form of an aqueous solution. OPTYSIL can be used together with other agrochemicals after conducting a miscibility test. Test results are presented in the table INTERMAG agrochemicals mixing table.
Detailed recommendations for foliar application are presented in the table below. You can also use the search engine and quickly find the dose rate and time of foliar application for your crop. Select your crop

FERTIGATION
Recommended solution: 50–270 ml of OPTYSIL in 1,000 l of ready-to-use nutrient solution.
Use in a separate fertigation cycle or together with fertilizers after checking if suitable for mixing.For soil-grown plants, use every 3–5 cycles of fertigation.
For soilless cultures, use for potting mats and several times during the plant growing season.
In strawberry cultivation, use up to 120 ml in 1,000 l of nutrient solution.

WATERING
Recommended solution: 0.1%, i.e. 100 ml OPTYSIL in 100 l of water. Water the plants 3–6 times during the growing season.
